Alignment and scattering of colliding active droplets
Kevin Lippera, Michael Benzaquen, Sebastien Michelin
Active droplets emit a chemical solute at their surface that modifies their local interfacial tension. They exploit the nonlinear coupling of the convective transport of solute to…
Bouncing, chasing or pausing: asymmetric collisions of active droplets
Kevin Lippera, Michael Benzaquen, Sebastien Michelin
Chemically-active droplets exhibit complex avoiding trajectories. While heterogeneity is inevitable in active matter experiments, it is mostly overlooked in their modelling. Exploi…
Collisions and rebounds of chemically-active droplets
Kevin Lippera, Matvey Morozov, Michael Benzaquen +1
Active droplets swim as a result of the nonlinear advective coupling of the distribution of chemical species they consume or release with the Marangoni flows created by their non-u…
No net motion for oscillating near-spheres at low Reynolds numbers
Kevin Lippera, Olivier Dauchot, Sébastien Michelin +1
We investigate the flow around an oscillating nearly-spherical particle at low, yet non-vanishing, Reynolds numbers, and the potential resulting locomotion. We analytically demonst…
Dynamics of anchored oscillating nanomenisci
Caroline Mortagne, Kevin Lippera, Philippe Tordjeman +2
We present a self-contained study of the dynamics of oscillating nanomenisci anchored on nanometric topographical defects around a cylindrical nanofiber -- radius below 100 nm. Usi…
